I've got a 2009 Intex pool that was full of tears and holes. So big in fact that I use fiber glass & epoxy to fix two, 3' long tears. I ordered this liner after already wearing out another liner that I bought 5 years ago or so. I fill the pool up yesterday and it is doing great. Just be careful as you unpack it and unfold it. It will probably tear if you get physical with it. But once it's in place and it gets cold from the water, it's pretty durable. My pool is 18' by 52". With this liner, I can get 4 more inches of water in the pool. I can fill it right to the rim.. But no need, it would just get splashed out in no time anyway.

This liner does the job it’s a good liner if you need a quick liner replacement don’t expect it to last a very long time but it does the job for the summer. Not the product company is fantastic! First liner we received was cut to pieces micro cuts you can’t see with the eye until the liner is stretched and then they would start pulling out to where you could see them. We contacted Amazon with not much help on replacement so we contacted the manufacturer and they was great! They sent us a replacement liner very fast it was here in two days and they provided a pick up return label so it was so smooth working with them. So anyone who purchases can be at peace of mind knowing the company will take care of you all you have to do is call!

Ordered for my 24’ pool hoping to have overlap. My pool was professionally installed and leveled correctly, the prior liner was perfect with plenty excess liner for over lap. This liner is THIN, holes near the top where the overlap should be on the pool, if it were long enough to even overlap.. overall a disappointing purchase, waste of money and time. Now I have to purchase another liner for $200+ and spend more time installing it. Would not buy this item again, and I suggest you don’t either - learn from my mistakes lol. I’d give 0 stars if it were possible. I have yet to hear back from this company on this item.

I have a 18ft diameter by 52in deep INTEX pool in which the liner sprung holes around the bottom seam over the winter. I bought this as a "fold over the top rail" replacement. I left the original liner in the pool to help support this new replacement liner. Because the liner was cheap, I was skeptical. But I have to say that it worked out really well, and so far it's held up. Now, it's just my wife and I, so we don't have little kids rough-housing in the pool. But even if we did, I think it would hold up just fine. The only challenge I had was locating the seams on the liner floor and making sure the ran parallel to each other on the bottom of the pool. Once they were aligned, then it was easy to push the liner out to the walls and drape over the sides of the frame. Time will tell how long it survives. But for a quick and cheap replacement, it has worked great for us!
